I love the big tense-up for the camera at the end when he kind of snarls and flexes his man-boobs.

Rrrrawwwwwrrr.

That's about the time he **** his pants. Again.

This is a common affliction. Its progression is as follows:
1. Study karate;
2. Realize you are not making the money you could running the McDojo you trained at;
3. Quit McDojo;
4. Reappear years later claiming to have inherited an unlikely ( impossible in the case of YAKUZA NINJA ) lineage from Japan;
5. Wear a black gi and a mask and hide in crab grass, waiting to leap out and molest female teenaged students ( or male students in some cases ), on Youtube.
